PRECAUTIONS
1 Observe the notes mentioned below when wiring to the power
supply terminal board.
Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely to the
terminal. Lock the wire down without applying excessive force to
the terminal. (Tightening torque: 1.31 N•m±10%).
2 Keep total current of crossover wiring between indoor units less
than 12 A. Branch the line outside the terminal board of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm
2
(Ø1.6).
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3 Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
4 Remote controller cords and wires connecting the units should
be located at least 50 mm away from power supply wiring. Not
following this guideline may result in malfunction due to
electrical noise.
5 For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6 Never connect the power supply wiring to the terminal board for
transmission wiring. This mistake could damage the entire system.
7 Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worst case, electric shock
or fire.
WIRING EXAMPLE
For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units.
Confirm the system type:
Pair type or multi system: 1 remote controller controls 1 indoor
unit (standard system). (See figure 18)
Multi system: 1 to 4 indoor units connected to 1 outdoor unit.
The indoor unit is controlled by a remote controller connected to
each indoor unit. However, the group control is not expected.
(See figure 19)
Group control: 1 remote controller controls up to 16 indoor
units (All indoor units operate according to the remote
controller). (See figure 20)
2 remote controller control: 2 remote controllers control 1
indoor unit. (See figure 21)
Figures 18, 19, 20 and 21
PRECAUTIONS
1 All transmission wiring except for the remote controller wiring is
polarized and must match the terminal symbol.
2 In case of group control, perform the remote controller wiring to
the master unit when connecting to the simultaneous operation
system (wiring to the slave unit is unnecessary).
3 For group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions
(as attached swing flap).
4 Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper ground-
ing could result in electric shock.
5 In case a shielding wire is to be used, connect a shielded portion
with the of a remote controller terminal board. (Also, connect the
ground for the remote control to a grounded metal part.)
1 Main power supply
2 Main switch
3 Fuse
4 Outdoor unit
5 Indoor unit
6 Remote controller (optional accessories)
7 Master indoor unit
8 Slave indoor unit
NOTE
It is not necessary to designate indoor unit address
when using group control. The address is auto-
matically set when the power is activated.
